Application Introduction:
In conjunction with the visual health and safety protection laboratory of China Institute of standardization, we jointly developed the "rhythmic light eye protection algorithm", which is specially customized for long-term eye use. After tens of thousands of tests, we found a more comfortable brightness curve for human eyes, and carried out up to 37 cyclic brightness adjustments every 60 minutes. This brightness change is difficult to detect by the naked eye, but it can keep the ciliary muscles in the eyes moving naturally, slow down visual fatigue, and make children's eyes relax as if they were outside the house. [18] [20] this is also the first eye protection platform that has passed the "Vico a" eye comfort evaluation of the bid winning Institute

Packaging:
Cautions:
The encapsulated material of the LEDs is silicone. Therefore the LEDs have a soft surface on the
Top of package. The pressure to the top surface will be influence to the reliability of the LEDs. Precautions Should be taken to avoid the strong pressure on the encapsulated part. So when use the picking up nozzle,The pressure on the silicone resin should be proper.
Soldering iron :
When hand soldering, the temperature of the iron must less than 300℃ for 3 seconds
The hand solder should be done only one times
SMT Reflow Soldering Instructions SMT :
Reflow soldering should not be done more than two times
When soldering , do not put stress on the LEDs during heating
The recommended reflow soldering profile as following
Handling Precautions :
Handle the component along the side surface by using forceps or appropriate tools
Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry
Do not stack together assembled PCBs containing LEDs. Impact may scratch the silicone lens or damage the internal circuitry
